The fourth season of Oprah’s Master Class kicks off with one of today’s most celebrated entertainers, multiple Grammy and Emmy award-winning actor and musician, Justin Timberlake, premiering Sunday, May 11 at 10 p.m. ET/PT on OWN: Oprah Winfrey Network.

Sharing never-before-told stories about growing up and his musical influences, JT lends his most valuable life lessons yet, including: how to find your voice, how to break the mold, and how to hold on to your ambition. In the exclusive clip above, Timberlake opens up about the importance of hard work.

“That was something I remember my parents telling me,” he says in the clip. “The idea that if you put in more than 100 percent, if you put in 115 percent, then there’s a good chance that you’re going to end up getting back somewhere in the 90’s. That made sense to me.

“And the idea that something worth having was worth putting all of yourself into it. Practice, rehearsal, working on it when no one’s looking. Getting comfortable in it. So that when you step on that stage, you’re ready. And then you can literally forget all of that and just be in the moment. And do something different. Do something original, do something different every time.”
